As the title suggests, I'm currently unable to add images or attachments to posts.

I can choose the file, but when I click to upload I get the following error message:

Testfile.jpg - Imageinfo Failed:
sh: /usr/local/bin/identify: No such file or directory

I'm posting this here largely so I have the error info in one place as we try to fix it, assuming it's not just a temporary problem. But I'm curious if anyone else is having the same problem.
